Sol sepatu adalah bagian terbawah dari bagian sepatu yang kontak langsung dengan tanah. Sol ini harus memiliki sifat fisik yang baik seperti tegangan putus, perpanjangan putus, Modulus, kekerasan, dan ketahanan. Sifat fisik barang jadi karet sangat dipengaruhi oleh perancangan awal formula kompon karet sol sepatu. Tujuan dari penelitian ini adalah untuk mempelajari pengaruh pemakaian IR 2200 dan KNB 40H sebanyak 10, 10.25, 10.5 phr terhadap sifat mekanik. Bahan digiling menggunakan dua rol terbuka, sedangkan pencetakan digunakan mesin hydraulic press. Hasil uji menunjukan bahwa vulkanisat karet dengan hasil terbaik diperoleh dengan pemakaian IR 2200 dan KNB 40H sebanyak 10.5 phr dengan nilai tegangan putus 13.42 MPa, perpanjangan putus 713,86%, kekerasan 67.8 shore A, ketahanan sobek 16.34 MPa, dan abrasi 0.22 cc. Hasil uji tersebut memenuhi persyaratan Nike Test Method.Downloads
